Application of Aromatic-Based Synthetic Macromolecules in Textile Wastewater

Abstract

AbstractWater pollution is reaching alarming levels recently and there is no longer any option to neglect developing an efficient wastewater treatment to protect our sustainable life. Among the harmful water pollutants, removal of synthetic dyes in textile wastewater is the most difficult process due to the high thermal and chemical stability of synthetic dyes. The high stability of synthetic dyes is a very serious issue because the degradation process is time-consuming. Furthermore, the high chemical stability of synthetic dyes also heightens the possibility of synthetic dyes spreading into a wider ecosystem and reaching the food chain. Because of the potential dangers, effort in the removal of synthetic dyes must be carefully considered. We summarized the recently published research on calixarenes and carbon nanotubes as promising aromatic-based synthetic macromolecules for synthetic dyes adsorption from both artificial and real textile wastewater samples through a commonly-used adsorption process. The adsorption process, well-known as the simplest removal technique, offers an easy operation and regeneration process. Furthermore, aromatic-based synthetic macromolecules, such as calixarenes and carbon nanotubes, exhibit high chemical and thermal stability as well as remarkable adsorption capability for synthetic dyes in textile wastewater treatment. Therefore, the aromatic-based synthetic macromolecules are potential candidates for textile wastewater treatment in the real-world applications.KeywordsDyesAdsorptionAdsorbentMaterialCalixareneCarbon nanotubeSupramoleculeAromaticSynthetic macromoleculesTextile wastewater
